Multiple default delivery days

We have two delivery days a week, any orders placed after Tuesday we have to manually move back to the following thursday

Thanks for the suggestion, but you should be able to do this already (assuming I’ve understood you correctly).

If you go to the delivery area and through to the edit screen, you can add an extra delivery date. Each time you edit, you can add one more date/schedule (pressing the Update button after each one).

If this isn’t what you’re looking for, please let me know, but hopefully this covers what you need?
